HYDROCARBON-BURNER.

Specification of Letters Patent.

Patented June 15, 1915.

Application filed February 23, 1915. Serial No. 9,861.

To all whom it may concern.

Be it known that I, BRADFORD A. THOMAS, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented new and useful Improvements in Hydrocarbon-Burners, of which the following is a specification.

This invention relates to a hydrocarbon burner.-

One of the objects of the present invention is to provide a simple, substantial, easily installed hydrocarbon burner adapted for use in connection with cook stoves, ranges or the like, and which is particularly constructed and arranged to handle low-grade fuel oils, such as distillate, or the like.

Another object of the invention is to provide a novel form of generating chamber in which the oil is vaporized before it is admitted to the combustion chamber, and also to provide a novel form of discharge nozzle by which the flame or discharge of gas may be regulated.

Further objects will hereinafter appear.

The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which Figure l is a central section of a furnace box showing the burner installed. Fig. 2 is an enlarged central section of the main generating tube and burner nozzle. Fig. 3

is a cross section on line 33, Fig. 2; Fig.

4c is a bottom view of Fig. 3.

The burner consists of a pair of connected generating tubes 2 and 3 to which oil is admitted and regulated by a valve 1. The oil is first admitted to pipe 2 where it is partly vaporized, and this vapor is conveyed by a pipe 5 to the main generating tube 3. The main generating tube consists of a pipe section 3, interiorly of which is mounted a pipe or tube 6 of smaller diameter. This inner pipe isperforated, as indicated at 7 and is spaced with relation to the exterior pipe by means ofa pair of caps 8-8, one being placed at each end of the pipe-6;

One of the caps is perforated, as indicated at 9, and the vapor admitted from pipes 2 and 5 is permitted to enter pipe 6 through opening 9 and is here further transformed formed between pipes 3 and 6. The inflammable product is here entirely completed and is discharged through a nozzle, generally indicated at A, in the following manner: The discharge nozzle consists of a casing 11 through which pipe 3 extends. A chamber 12 is formed in the lower end of this casing and an opening 13 formed in pipe 3 permits the gas in the annular chamber 10 to escape into the chamber 12. A cap 14 turnably mounted on the lower end of the casing 11 forms a valve by which the discharge of gas'from chamber 12 is regulated and controlled.

An opening 15 is formed between chamber 12 and cap let and this opening is adapted to be brought into communication with a plurality of openings 16 formed in the cap. These openings are graduated in size and the turning of the cap permits the volume of gas discharging to be regulated in this manner. The cap 14 is secured on the end of the casing 11 by securing thereto a forkshaped strap 17 which straddles pipe 3. A set-screw 18, passing through the strap or bail' and engaging a socket in the top of the casing, permits the cap and strap to be turned by means of a socket wrench or like means.

Mounted in the furnace, below the nozzle A, is a baffle or deflecting plate 20. This plate covers pipe 2 and prevents same from becoming overheated. It also serves as a means to direct the flame in the desired direction.

A burner constructed and arranged in the manner shown is particularly capable of handling low-grade fuel oils, such as distillate, and the like, as the oil is gradually heated and transformed before it is discharged through the burner nozzle. The gradual heating and transformation provided iii this instance practically eliminates carbonization at any point and what little the end cap 21' and removing the inner generating tube 6.

The graduated discharge openings formed in the cap 14 permit a flame area of practically any size and, furthermore, permits two or more of said nozzles to be mounted on one pipe and controlled by the single valvei, as the discharge opening 15 may be entirely closed by turning the cap into an intermediate position. Thus two or more nozzle burners may be mounted on the same generator and one or any number ofsame may be turned off or in use. The provision of the baffle plate 20 prevents the lower or primary generating tube from becoming over heated, thus preventing carbonization at this point.

The materials and finish of the several parts of the hydrocarbon burner are such as the experience and judgment of the manufacturer may dictate.

I wish it understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims, and that I do not wish to limit myself to the specific design and construction here shown.

Having thus described my invention, what I claim and desire to secure by Letters Patent is- 1. A hydrocarbon burner comprising a horizontal generating tube, a concentric inner tube of smaller diameter forming with the outer tube an annular generating chamber, said inner tube having equally spaced openings through which a regulated flow is distributed from end to end of the inner tube, a burner nozzle including a vertical casing through which the generating tubes pass, said casing having a chamber below the generating tube, a passage from said tube to the casing chamber, a cap turnably mounted on the bottom of said nozzle chamher having a plurality of graduated discharge openings, and means to turn said cap to control said openings and regulate the discharge. 1

2. A hydrocarbon burner comprising a generating tube, a nozzle casing through which said tube extends, said casing having a. chamber formed therein and a discharge opening, and said generating tube having an opening formed therein communicating with the chamber and discharge opening in the nozzle casing, a cap having a plurality of graduated openings formed therein mounted on the nozzle casing, a. bail secured to the cap and extending over the nozzle casing, a plvot screw extending through the ball and engaging with the nozzle casing to secure the cap on the nozzle, said screw also forming a means for turning the bail and cap to bring any one of the graduated openings in the cap into register with the discharge- Goples of this patent may be obtained for five cents each, by addressing Washington, D. 0.

opening in the nozzle casing, and means for admitting oil to the generating tube.

3. A hydrocarbon burner comprising a generating tube, a nozzle casing through which said tube extends, said casing having a chamber formed therein and a discharge opening, and said generating tube having an opening formed therein communicating with the chamber and discharge. opening in the nozzle casing, a cap having a plurality of graduated openings formed therein mounted on the nozzle casing, a bail secured to the cap and extending over the nozzle casing, a pivot screw extending through the bail and engaging with the nozzle casing to secure the cap on the nozzle, said screw also forming a means for turning the bail and cap to bring any one of the graduated openings in the cap into register with the discharge opening in the nozzle casing, a perforated tube interiorly of the generating tube and spaced therefrom to form an annular generating chamber, and means for admitting and regulating a flow of oil to said tube.

4. A hydrocarbon burner comprising a generating tube, a nozzle casing through which said tube extends,said casing having a chamber formed therein and a discharge opening, and said generating tube having an opening formed therein communicating with the chamber and discharge opening in the nozzle casing, a cap having a plurality of graduated openings. formed therein mounted on the nozzle casing, a bail secured to the cap and extending over the nozzle casing, a pivot screw extending through the bail and engaging with the nozzle casing to secure the cap on the nozzle, said screw also forming a means for turning the bail and cap to'bring any one of'the graduated openings in the cap into register with the discharge opening in the nozzle casing, a perforated tube interiorly of the generating tube and spaced therefrom to form an an nular generating chamber, a second generating tube mounted below the first named generating tube and connected with said tube and the perforated tube interiorly thereof, and meansfor admitting andregu- 'lating a flow of oil to the second generating tube.

In testimony whereof I have hereunto set my hand 1n the presence of twolsubscribi'ng wltnesses.
